The above message contained the following:

Odd.  I expected one of them to fail.

Let's make a slight change that brings the script closer to the one that
failed.  What does this script do?

   touch /tmp/$dayOffsetName
   sleep 2
   cd /tmp
   if find . \! -name . -prune -mtime 0 -name $dayOffsetName |
            grep $dayOffsetName >/dev/null 2>&1; then
       echo DAY_OFFSET=1
   elif find . \! -name . -prune -mtime 1 -name $dayOffsetName |
            grep $dayOffsetName >/dev/null 2>&1; then
       echo DAY_OFFSET=0
       echo "Couldn't discover meaning of '-mtime' argument of find(1)"
       exit 1

Make sure that you're executing the script with the same user-shell that
crontab(1) will use.
